#1: Air horn help! Author: Rob2859, Location: HalifaxPosted: Thu Aug 26, 2010 7:34 am ---- Well I went into the yorkshire trading company (former woolworths in my town) and found everything in there was crap. then I found a not too bad car section which I bought for £12.99! I had to have it for the price. Bought some nice mats too. But anyway...
I failed to wire it up. I have mounted the compressor and the trumpets in the corner behind the battery but was stumped by the wiring. Not just from the fact that I have no understanding of relays but I don't know which is live and which is earth on the original horn.
Help please? I cut the plug off the end but I have a pink wire and a yellow wire with a green strip on it. (it might be the other way around actually).
Can someone tell me which is the live? At least thats a start.
Also the instuctions which are now lost told me to earth the relay. Could I not just use the earth cable on the original horn?
Thanks guys

#3: Re: Air horn help! Author: Rob2859, Location: HalifaxPosted: Thu Aug 26, 2010 7:43 am ---- The instructions told me to earth the relay and just leave the earth on the normal horn. That doesn't make sense. Should I just use the earth on the horn?
#4: Re: Air horn help! Author: fps_cod, Location: Hereford/CardiffPosted: Thu Aug 26, 2010 8:16 am ---- If your wiring it to the original horn cables then you don't need a relay, as apparently the horn already has one? (I didn't use one... Maybe somebody else could confirm it, but i had no problems) Just connect the compressor cables to the orignal horn ones one way then test the horn..(connect the tubes to the horns too) If if comes on but doesn't make a noise then it's sucking, just connect the cables the other way. That how i worked it out anyway.
Hope it helps.
#5: Re: Air horn help! Author: vintageoriginal, Location: London, UKPosted: Thu Aug 26, 2010 8:38 am ---- Correct, you don't need the relay. I have air horns and they are wired directly.
#6: Re: Air horn help! Author: Rob2859, Location: HalifaxPosted: Thu Aug 26, 2010 12:27 pm ---- cheers for the info guys will have to try it out when i get some wire that doesn't melt
#7: Re: Air horn help! Author: V9977, Location: Athens, GreecePosted: Thu Aug 26, 2010 5:42 pm ---- I have a 1.4 and a rellay is included in the horn circuit as standard.
This can be seen on the bottom right hand corner inside the engine bay
fuse box and can supply up to 35A to the horn.
So there's little point in adding another rellay in that case.
However, I don't know if the 1.1 has one (check first) otherwise you will
damage the steering wheel horn switch with the much heavier current of the
air compressor - guaranteed.
Also, if using the standard rellay of the fuse box and not adding another,
you must uprate fuse F5 (First one on the bottom group in engine bay fuse box) from
15 to 25A (white) which is actually perfectly acceptable and is specified
as an option in the manual.
In any case proceed with great care and don't rush.

So if I have a relay then All I need is a fuse? Would have thought the 1.1 has one as it is proberbly the same horn. Can anyone confirm? Will have to see if I can find it in the haynes manual. Although I need to find the haynes manual first
Thankyou thats a big help.
#9: Re: Air horn help! Author: V9977, Location: Athens, GreecePosted: Fri Aug 27, 2010 4:58 am ---- Haynes doesn't have it.
Look on the bottom right-hand section of the fuse box.
If there are two rellays then the bottom one is for the horn.
You can confirm this by unpluging the rellay momentarily
(with engine off) and trying the horn. If it doesn't sound, that
is your horn rellay.
If there is only one rellay in that area it could be that the horn
is fed directly from the steering wheel switch in which case you
definately need an external rellay added.

#11: Re: Air horn help! Author: Golfguy206, Location: PeterboroughPosted: Fri Aug 27, 2010 5:04 am ---- speak to ExoViper - fitted his with a relay to his twingo!
#12: Re: Air horn help! Author: Rob2859, Location: HalifaxPosted: Fri Aug 27, 2010 5:08 am ---- If I need to use a relay then I will ask my mate as he has done it on his corsa. If I could just do it straight to the horn then that would be a bonus
#13: Re: Air horn help! Author: V9977, Location: Athens, GreecePosted: Fri Aug 27, 2010 5:15 am ---- No problem if you've unpluged the horn, just listen
for a 'click' sound coming from the fusebox everytime
you press the horn switch in that case.
#14: Re: Air horn help! Author: Rob2859, Location: HalifaxPosted: Fri Aug 27, 2010 5:16 am ---- Yes I think I did hear one. will have to double check though don't want to burn out the switch
#15: Re: Air horn help! Author: V9977, Location: Athens, GreecePosted: Fri Aug 27, 2010 5:20 am ---- If there is nothing connected how will the switch burn-out?
If there is something connected just unplug the said relay
and see if that stops it from working. This is quite safe with
no key in the ignition.
#16: Re: Air horn help! Author: Rob2859, Location: HalifaxPosted: Fri Aug 27, 2010 5:28 am ---- I mean wire the horn in and burn the switch on the steering wheel. I will go have another look I couldn't see a fuse marked F5. they were just numbers, no letters

53. I have a 15A fuse in the bottom right hand corner but its not F5
#19: Re: Air horn help! Author: V9977, Location: Athens, GreecePosted: Fri Aug 27, 2010 5:51 am ---- Yours is plexed so have a look here:
#20: Re: Air horn help! Author: Rob2859, Location: HalifaxPosted: Fri Aug 27, 2010 6:08 am ---- Cheers. will let you know how i get on
#21: Re: Air horn help! Author: Rob2859, Location: HalifaxPosted: Wed Sep 01, 2010 8:37 am ---- Finally got some cable. wired it directly to the old horn and put a 30A fuse in. Thanks for the info guys. Saved myself a lot of time and wire
#22: Re: Air horn help! Author: V9977, Location: Athens, GreecePosted: Wed Sep 01, 2010 8:43 am ---- Excellent. Horns save lives btw.
I would go for 25A fuse (white or clear) when you have one.
This is specified as an option in the manual and you would
be doing things by the book then.
#23: Re: Air horn help! Author: ExoVyper, Location: Waiting for the tugboats to push me into port (Whitehaven)Posted: Wed Sep 01, 2010 9:31 am ---- argh!!! you NEED a relay in the wire!
i learned the hard way on my old 106 when the stalk started smoking trying to melt :S
relays are really easy to put in when i get home and onto proper internet i'll draw a picture for you and post it up
#24: Re: Air horn help! Author: ExoVyper, Location: Waiting for the tugboats to push me into port (Whitehaven)Posted: Wed Sep 01, 2010 9:32 am ---- also as an added bonus a horn plugging into a relay can use the full amperage of the battery so it's louder
#25: Re: Air horn help! Author: V9977, Location: Athens, GreecePosted: Wed Sep 01, 2010 11:28 am ---- No, the 206 already has a relay for the horn, confirmed. (see thread)
It would be pointless to add another relay in this case.
EDIT: I know this because I took your warning very seriously
when I was fitting mine and it turned out there already was one.
So cheers to ExoVyper for the heads up.
#26: Re: Air horn help! Author: ExoVyper, Location: Waiting for the tugboats to push me into port (Whitehaven)Posted: Wed Sep 01, 2010 12:19 pm ---- ah right
i always put one in which ever car i get after the close call in my old car lol
my apologies ^_^
#27: Re: Air horn help! Author: Rob2859, Location: HalifaxPosted: Wed Sep 01, 2010 6:09 pm ---- much better than the old horn that was rubbish
